To @ZZ-whom it 71mg/ concern;

Be it known that I, JOSEPH M. NORMAND, a citizen ofthe United States, residing atSpringfield, in the county 'of `Clark and State of 5 Ohio, have invented certain new and useful Improvements in Pumps, of which thetollowing is a specification. f

My nvcntion relates to `improvements in pumps.

xo `The object of my invention is vto providea pump particularly adapted f or deepwells and A other wells where, for reasons connected with theconstruction of the well, but asingle pipe can'bc inserted-such forexai'npleyas drivenv r 5 or bored-wells.

My' invention consistsin the various con 'st-motions and combinations of parts, h erein after described and claimed.

In the accompanying drawings, Figure l is zo an elevation view of a pump, partly in section, embodying my invention.. Fig. 2 'is a detail View in section of the hollow plunger, 'sho'winga modification. ini-thev manner of "at,- -taching the lower plunger-rod. Fig. 3 is a 25 transverse sectional view of. the same. Fig. 4 is a sectional elevational view ofthe lowerplnnger and .the lower valve. l

Like parts are indicated by similar letters of reference throughout the several views. 3b In the said drawings, Arepresents the main pipe and outer .casing ofl the pump, which also forins the pumping-cylinder. :This pipe A'is of a uniform diameter throughout and ex'- tends from the top tcv the bottom of the well.' 35 .Athree-waychamberl3ispreferablyconnected in thepipe' to forma dischargeopening from said pipe. This threeway chamber B preferably provided with an auxiliary chamber B', parallel with the main pipe A, tothebotj- 4 tom al1d top, respectively, of which are ati tached'exit-pipes C C. 'j The upper ezdt-pipe C extends upwardly along the main' pipe or stock iA, and is provided in .the'usual manner lwith a discharge pipe or spout C2, the lower'y 45 exit-pipe C.. being adapted to act as a distributing-pipe-to carry the Water many con'- venient point desired.v A valve D, located in the auxiliary chamber B and connected to a below the said valveseats.

- 'valvesteln D', 11s adapted when in one pesif-l tion to close 'the lower extpipe Cfat the-5.o same time the `upper exit-pipe is lertopen, and adapted when in another position to close the upper exit-pipe and at the saine time open stuffing-box connection D3 being;l providedin the discharge-pipe G2 to prevent leakage and at thesame time furnish means for'lioldiug the Valve in diiercnt positions of adj ustzneut. The aumllian-3 7` chamber E is provided' Vwith Y`v alve-seat s :i: fr, formed integral wvl/in the main casting of the three-Way chamber and on' either side'of the opening between the main chamber, and the auxiliary chamber B". By this construction the valvegseats are 'independentof the' pipefconuections :from the exit-opcningazwliich"are located .above and The lower main valve of the pump is formed, in the nature of a plunger E, to tightly into the pipe A, and provided, in the usual manner, with a central disk-valve ll,

The outer or. plunger portion E o' valve is secured on the end oi' a short stem E2, which extends upwardly int-o a sleeve E?, funerarios the main plunger-rod, the plunger-rod being' so constructed. as te admit of a limited lengt. tudinal movement ou the stem E2, the 'said Se stem E2 being provided with ahead E3, which prevents'the stem' from being withdrawn 'from said chamber, so that when the main plunger-- rod is moved upwardlyfor an unusual (listance the lower plunger apdfvalve will Withdrawn from its place and may be cari; upwardly th-rougb-the-maiu pipe A with vtiro said. plungerrod, the construction of the lower valve E being* substantially as set fortli in my Letters Patent No, 378,848, ci February a 28, .1888. v

F Frepresent the main plunger, which preferably constructed with two pistons, so' as to secure a better-bearing in the main This plungeris secured to the lower rali? as above described, andl iscouaccicd main plunger-rod if", which entends n through the main conne receso Extend.' 4 lloll'llwllll'lly illroufgll tlle top of 'tbe golpe ll lo ll'illlin :l sllort distance ol' ille three-Waff clllllnber ll is al llollou' plunger-rod rlllis llollol,Y llllnucnroll L? is closed at the loll and eonnecled lo ln' lnaill plunger' roll l1" in su ll ll lnellller lllni Llley botll more together. .lt preferably lnllde of pipe of a suitable size so lllet tlle internal alrezl of said pille is equal lio e' ,lut llnllf the area olf tlle lnaill. pine jl..

Vllle operation ol the puinll as described is us ollolls: The lower plunger and lllo lower main valve are inserted through the pipe A until :lll-.id valve is in proper position for operation. j ust above il nulil'l Vdull linneo obo e-llay chamber l5, the lower located a vsuitable lisllle :nulli rallye E.

When ille water llas been elevated su llicieutly to be discharged through the discharge-pipes C3, the water ill the llollowplllngcr G serves as a stand-pipe, into wllicllabout'half the Waier of each stroke is forced on tlle downstrokc of ille plunger, and by its own weight is forced ont ci' lille dischange-pipeC2 on the upstroke of ille plunger, thus forming a substantially continuous discharge at tli e discharge-pipe C2.

'When it isdesired to operatetlle pump as a force-pump, the valve. I `is' closed andthe column olf 'water sjreplaced by a column of air, which lllls tllehollow plunger, 'forming an airfcnsllion, against which ,the water-'is forced at each successive stroke 'and from which it is expelled by the air-column, tllus formingsubsiantially acontinuous discharge.

Having thus described my invention. I claim- 1.
